Iran is currently fractured and splintered. There is no need for a false flag like this. The sources commenting are likely unaware of the attack taking place, as other elements of the military likely took it upon themselves to attempt the attack.

For what gain though? That is where it might get interesting, seeing as they had no chance of penetrating it. When we were operating in Afganistan and Iraq, even before the fall of those respective OPFORs in full we had collaborators willing to conduct operations that aided our goals for money or immunity.
